[Intel-gfx] [PATCH 0/7] wait_for and wait_until_reg

[Mika Kuoppala]

I resurrected this series as there was irc discussion about wait_for
and it shortcomings. I have wait_until_reg conversions also 
as individual patches per file if that makes things easier to digest.

If we decide to go this route,

text	   data	    bss	    dec	    hex	filename
1166505	  24385	    920	1191810	 122f82	drivers/gpu/drm/i915/i915.ko.nightly
1155137	  24385	    920	1180442	 12031a	drivers/gpu/drm/i915/i915.ko

we save 11368 bytes.

Mika Kuoppala (7):
  drm/i915: Remove the wait_for_us macro
  drm/i915: Use milliseconds in _wait_for macro
  drm/i915: Spin opportunistically in wait_for
  drm/i915: Take longer naps in wait_for
  drm/i915: Introduce wait_until_reg
  drm/i915: Use wait_until_reg macros
  drm/i915/debug: Warn when waiting on condition timeouts
